Time difference & DST
Japan Standard Time is 14 hours ahead of Eastern Standard Time, or 13 hours ahead when New York is on daylight saving time. The wide gap effectively puts the two workdays on opposite sides of the clock face.
Japan does not observe daylight saving time; JST is fixed at UTC+9 year-round. The offset with EST therefore compresses by an hour every summer while the US East Coast is on EDT.
Best time to schedule a call
Tokyo mornings pair naturally with New York evenings. Try 8:00 PM EST, which lands at 10:00 AM JST the next day and gives Japanese teams a fresh-day feel without asking anyone in New York to work past mid-evening.
